WAGON-BRAKE SHOE.

SPECIFICATION forming part of Letters Patent No. 234,435, dated November 16, 1880.

Application filed July 16, 1879.

To all whom it may concern Be it known that I, CHARLES A. SKENE, of Westmoreland, in the county of Pottawatomie and State of Kansas, have invented a new and lmproved Wagon and Carriage B rake, of which the following is a specification.

The object of my invention is to furnish an improved wagon or carriage brake-block which shall be simple in construction and permit of readily changing or renewing the shoe.

It consists of a block of wood or other suitable material, to which a fixed plate and a slidin g plate, both provided with dovetail flanges, between which the shoe is clamped, are attached in such a manner that by means of a set-screw the shoe may be loosened or retained, all the parts being constructed and arranged as hereinafter more fully described and claimed.

In the accompanying drawings, Figure l is a front elevation of the block. Fig. 2 is a vertical longitudinal section on the line 00 an Fig. 3 is a horizontal crosssection on the line y 1 Similar letters of reference indicate correspondin g parts.

A is a block of wood or some other suitable material, and is mortised for the reception of the cheeks J and K, attached to the plates 0 andD, respectively. The plate 0 is securely fastened to the block A A by the screws N N, or some other suitable means, and the plateD is fastened by the screw 0, which passes through the slot M, and thus allows it to move to and from the plate 0.

The slideD is adjusted by the screw H, which passes through the cheeks J and K and into the block A.

The check K is provided with a threaded screw-hole, E, but the cheek J has a recess, R, the sides and top of which fit closely into an annular groove, L, in the shank of the screw. If the screw is turned, it cannot move in either direction, as it is held by the cheek J but the screw taking in the threads of the hole E will cause the cheek K, and with it the slide D, to move to or from J, according to the direction in which the screw is turned.

B represents a brake-shoe of leather, rubber, or some other similar or suitable elastic material.

The parts 0 and D are first drawn apart, the shoe is inserted, and the screw H drawn tight, thereby causing the parts 1) and O to approach and the shoe to be firmly clamped between their dovetail flanges.

The angular barbs PP are to prevent the shoe from being drawn down by the wheel when the friction is very great.

The shoe, block, and the several parts may be made of wood, iron, steel, or some other suitable material. The blocks are to be so arranged that the heads of the screws are to the inner side of the wheel. Without any inconvenience and without much time or labor the shoes can be renewed or adjusted.

The plates form avery slight dovetail, so that when the brakeis applied the wheel forces the shoe down into this dovetail.

I am aware that it is not new to make a brake-block movable or adapted to suit the dishing ofthe wheels; but my invention is simply a means of attaching and holding a rubber upon the face of a brake-block so as to take up wear and allow the easy replacement of the rubber.

What I claim as new is The combination of the mortised block A, stationary flanged plate 0, having cheek J, adjustable flanged plate D, provided with cheek K, elastic shoe B, and adj Listing-screw H, having annular groove L, the said plates being also provided with angular barbs P P, adapted to embed themselves in the body of the shoe and hold the same securely against frictional strain, substantially as set forth.

CHARLES AQSKENE.
